This invention relates tothoseharvesting vmachines which trim the productsdumped into them, removing the excess leaves, roots, and non-essential growths for making them 5 more presentable as marketable produce, or, as product to be further treated as in pickling works and canneries.

The objects of the invention, are :-The providing of a portable machine that may be easily shifted to the varying positions necessary in its intended servicing of the harvesting crews in the field where a device of this kind is employed. The providing of a suitable machine into which may be dumped the products taken from the soil so that these products will be trimmed and directed to other containers used in conveying them from the harvest field. The providing of a device light enough to be manually directed about the field of operations wherein the machineis being employed, and constructed in sucha manner that the device may be easily shipped to distant points within containers of minimum volume for economizing in the '25 costs attending thev shipment of freight of this classification. The providing of a power unit adjacent the operative means the said power unit actuates, for allowing a short belt to connect up the said source of power, which condition takes advantage of the action common to short looped belts, the feature of slipping their pulleys, and the advantage of easy replacement againof the displaced belt. This advantage is of great value when obstructions get between rotating parts un- Other advantages will be'notedthroughout the specification and particularly pointed out in the appended claim; reference being had to the accompanying drawing, the

several views of the latter being indexed as 001 follows Figure 1 is a side elevation of the ma? chine. i a

Figure 3is a. section on line 3-3 of Fig. 1. Figure 4 is a fragmentary view with bar vested products shown between the rolls. Figure 5 is a transverse View of the nipping rolls.

Similar characters of reference apply to like parts throughout the several views.

A :framework or chassis C, comprises channel iron side members .S that are held in spaced relation by a motor unit.M,,a gear housing H, and an end casting E; These ale 2% ments along-with suitable wheels W, mounted uponafixed rear axle and a swingable front axle complete the portable assembly whichis easily maneuveredmanually about the field of operations, and, of course, there is the usual provisions whereby the device may be readily transported to distantly removed locations with the aid of any suitable draft means. h

The housing IT and the end casting E have supporting planesupon whiclris carried a hopper-chute G that is, inclined to induce products dumped therein to travel towards the discharge end whereat is attached an apron A that holds whatever containers appropriate for receiving the produce being harvested. The chute G is open at its bottom, between the'h ousing H and the casting E, except for a pair of opposedly rotating rolls, which partially close the said bottom, the aforesaid rolls offer a twisted rectangular gember R, and a plain cylindrical member \1 The rectangular roll R is given a half turn, that is, a corner a, at the housing Hwill be the corner 5 at the casting E, see Fig. 5. The rolls rotate at uniform speeds, and the elongated spiral edge offered by the corners of the rectangular member R, gathers the tail like roots and the leaves into a swiftly moving wedge-shaped valley V where the oncoming spiral edgepinches them-against the roll R whichaction nips them off and carries the refuse beneath where it falls to the ground, and, at the same time compels the desirable portions of the harvest to find the containers at the discharge end.

7 The rolls R and R are reduced at their ends to provide axial 'trunnions, RI at the casting E, and R 3 at the housing H. Suitablebores inthelcasting E function as journals for the trunnion studs R and a'similar provision obtains at the housing for the trunnions R and B In the case'ofthe latter trunnions-ea'ch will have keyed there-4 v lar roll twisted to offer spiral ridges thereon,

on similar s ur inions I and I meshed together for rotation as per arrows shown.

The trunnion R is extended to accommodate a mitre gear 2 that is in mesh witha similar gear 3 keyed to a drive shaft 4 Which'la'tter is journalled in theside Walls of the housing H; this shaft'p rojectsbeyond. the housing to receive a drive pulley P that is geared to an engine pulley P by means of a short belt loop The object of the short belt'is to allow the said belt to readily slip off the pulley V P" whenever any obstruction gets between the rolls whose spaced relation-is fixed, the

'The housing H is provided-with a cover plate 5 which completesa dustproof chamber '1 wherein is confined the principal frictional assembly, and this assembly is arranged to run in; grease. The said housing, being of box-like design, lends itself to the simpler forms of shop fixturesfor machining same accurately-and rapidly, both'in the matter of its 7 employment as a spacer-support, and, as a multiple bearing element forthe shaft 4 and the roll trunnions R and R VVith this element in position the assembling of the remainder of the machine is an easy performance that can be accomplished by labor of the mediocre type. V v s The machine is composed of simple elements arranged with a view toobviating the outlays occurring through costly service fees thatobtain where the devices are complex in structure and requiremore than the ordinary skillabounding in the localities where devices of this classification are in demand.
